We present a novel approach to Bell tests that eliminates coincidence windows while simultaneously addressing multiple experimental loopholes. Using dual-quadrature homodyne detection with randomly selected measurement angles for each ensemble of photon pairs, we demonstrate that quantum correlations can be verified through ensemble averaging without real-time coordination between spacelike-separated detectors. Alice and Bob collect completely independent measurement streams which, when post-aligned through bit-shift analysis, reveal quantum correlations only at perfect stream alignment with statistical significance beyond 100σ. This ensemble-level verification with random settings per ensemble simultaneously addresses the coincidence window problem, the fair sampling loophole, and the settings independence loophole, while proving that correlation information emerges through proper ensemble alignment without requiring real-time spacelike coordination.
